New variations
on old themes
By IM Merijn van Delft & IM Robert Ris
Frequency
In this issue of CVO we take a look at the Austrian, Belgian
and Czech Leagues, the German National Championship
and other events including the Cappelle la Grande Open.

Score
In his game against Rasulov, Harikrishna once again showed that the
white pawn on b3 can become terribly weak in the Berlin Endgame (we
discussed this theme in CVO 137). Balogh-Gustafsson is the latest
news from the Archangelsk front (see below).
Rodriguez Vila-Vescovi (Najdorf 6.h3) demonstrates the famous
Velimirovic sacrifice (¤f5 followed by ¤d5, see CVO 22 for some classic
examples) and is a good reminder of the energy that White generally
needs to put into his attack in the Open Sicilian. Below we take a look
at Bartel's tricky move order versus the Paulsen. Volokitin-Jobava
provides study material for the Caro-Kann Advance Variation.
Gyimesi is a true 1.d4 expert. His game against Bromberger was a
King's Indian gone completely wrong for Black and below we have a
look at his Semi-Tarrasch game versus Socko. Khenkin-Stern was an
interesting white approach against the QGD. Le Quang Liem-Ni Hua
was a tough battle in the Slav between two elite Asian players. Laznicka
beat Matlakov in the Semi-Slav with 5...a6 (see below). Our
Game of
the Week
saw Van Wely produce a model game against Ikonnikov, who
went for 6...¥xd2 in the diagram position.
Source: Megabase + TWIC, 2500+ only
Van Kampen was the top seat in the Amsterdam Batavia Tournament, but finished a very mediocre event with a terrible blunder and
thus a quick loss against Hebden. The first 16 moves of this game were in fact discussed in CVO 159. By that point Black already
enjoyed full compensation for the sacrificed pawn and most likely knew exactly what he was doing. The
moral, of course, is that failing to carefully read your weekly CVO can cost you dearly!

Reviving an old Queen's Indian
In the following game Ikonnikov tried an old Ulf Andersson line but never managed to
equalize completely. In the end Van Wely instructively transformed his positional edge into a
strong initiative.

12.e4 ¤c6 13.¤xc6 dxc6 14.e5 ¤d7 15.f4
¤c5 16.¤f3 a5
Sooner or later this move has to be played in
order to keep the ¤ on c5. Less accurate is
16...£xd1 17.¦axd1 followed by ¤d4 (attacking
the pawn on c6) and doubling ¦s on the d-file,
when White retains a nasty advantage.
17.£e2 ¦a7
It seems more natural to connect the ¦s and
prepare for massive exchanges on the d-file
with 17...£c7.
18.¦ad1 ¦d7 19.¦xd7 £xd7 20.¦d1 £c8
21.¤g5 g6
21...¦d8? fails to 22.¦xd8+ £xd8 23.£h5 and
White wins. 21...h6 22.¤e4 ¤xe4 23.£xe4
leaves the pawn on c6 vulnerable.
22.¦d6 ¦d8 23.£d1 ¦xd6
Ignoring the exchange of ¦s with 23...¦e8 is
hardly an option now, because of 24.£f3 and
Black gets into trouble.
24.exd6
The only chance to fight for an advantage.
Nothing can be gained from 24.£xd6 when
Black can simply wait.
24...f6 25.¤f3 ¢f7 26.£d4 £d8 27.g4 ¤b7
27...¤d7 28.g5 f5 29.¤e5+ ¤xe5 30.£xe5

33.£xe6+ £e7 34.£xc6 £e2+ 35.¢g3 £xa2

29.h4
The immediate 29.g5! would also have been
strong.
29...¤c5 30.g5 e5?
Harakiri, but alternatives aren

30...£xd7 31.£xf6+ and Black

falls apart. 30...¤xd7 31.gxh6 £e7 32.£e4
and the pawn on c6 falls, as 32...c5 can be
met powerfully by 33.h5!. The most stubborn
defense would have been 30...hxg5 31.fxg5
¤xd7 32.gxf6 ¢e8 (32...c5 drops a piece, in
view of 33.¤e5+ ¢e8 34.f7+ ¢f8 35.£d6+

Of course not 32.£d6? £xd7 and Black
survives.
32...hxg5

1–0
1.d4 ¤f6 2.c4 e6 3.¤f3 b6 4.g3 ¥a6
There was a time when Black would
automatically play 4...¥b7 . In CVO 159 we
covered a relatively unexplored idea which
caught leading expert Tiviakov by surprise.
5.b3
At one time this move was played almost
exclusively in this position. In the last couple
of years White has employed 5.£c2 (CVO 11,
63 and 68) and 5.£a4 (CVO 16, 48 and 93)
more often.
5...¥b4+ 6.¥d2 ¥xd2+
A very solid, but passive continuation which
came into fashion towards the end of the
seventies due to the efforts of the Swedish
legend Ulf Andersson. Nowadays Black
usually opts for 6...¥e7. In CVO 60, 64 and
68 we reviewed the current state of that
variation.
7.¤bxd2
The other recapture 7.£xd2 has been played
more frequently and is perhaps more critical.
In fact, Van Wely had played it twice before
(though without success), while last year
Levon Aronian defeated Nigel Short in a
technical encounter during the London Chess
Classic.
7...¥b7 8.¥g2 c5 9.0–0 cxd4
Another high-profile game went 9...0–0 10.£c2
¤c6 11.£b2 (11.dxc5 bxc5 12.¤e4 ¤xe4
13.£xe4 £e7 14.¦ad1 d6 is OK for Black.)
11...¤xd4 12.¤xd4 ¥xg2 13.¢xg2 cxd4
14.£xd4 d5 and Black comfortably equalized
in Andersson-Short, Naestved 1985.
10.¤xd4 ¥xg2 11.¢xg2 0–0
11...a6 12.e3 (12.e4!? might be more
challenging.) 12...0–0 13.£f3 ¦a7 14.¦fd1

As we pointed out in CVO 86, the pseudo-sacrifice ¤xe5 can be quite a tricky line to deal with as Black,
especially the new version with White leaving the a-file closed for the time being. White gets the pair of
bishops, but has to deal with Black's dynamic counterplay. 12.£c3 ¤e7 13.£d3 has been White's choice so
far, and Black's best course of action here may be 13...c5 14.axb5 axb5 15.c4 0–0! 16.cxb5 d5! 17.exd5 ¥f5
18.£c4 ¤exd5 with good chances of equalizing. This week in Balogh-Gustafsson, White played the immediate
12.£d3!?, which is in fact a novelty. Black's 14...¥e6?! looks like an inaccuracy, with 14...bxa4 15.¥xa4 ¥d7 a
critical alternative. In the diagram position the modest 18...¦a8 may give better chances of holding the position.
In the game Gustafsson played more actively with 18...c5, but following 19.e5 Balogh got an initiative that proved
decisive in the endgame. On a side note, this week's Antoniewski-Ragger saw 8.c3 d6 9.axb5 axb5 10.d3,
which didn't really worry Black.

The Sicilian Paulsen can be quite a move order labyrinth, which was confirmed by Bartel-Petr, played in the
Czech League this week. Black's 5...£c7 may actually be less flexible than the more common 5...¤f6 6.0–0
£c7. Or would Bartel have delayed castling in that case as well? By playing 6.£e2 d6 7.b3!? Bartel discourages
his opponent from going for a setup with ...g6, which is seen as Black's most critical course in this branch of
the Paulsen. The position after 12 moves is more frequently reached by a different move order. By putting his
¤ on d2 instead of c3, White can play ¤2f3 later on to defend his far advanced e-pawn. With 15...dxe5?! Petr
probably committed an inaccuracy, with the immediate 15...¤h5 being the critical move and leaving the position
very explosive. In the diagram position Black panicked with 19...f5?, giving White an attractive attacking position
for free. 19...b5 had to be tried instead. If Black wants to avoid these kinds of position he's best advised to stick
to the modern main line with 5...¥c5.

In CVO 29 and 100 we extensively covered the current status of theory in the Semi-Tarrasch. Before entering
the masses of variations both sides have to know, White has an interesting side-line at his disposal. White can
delay the development of his king's ¥ with 11.¦c1!? and in case of the careless 11...¤c6 Nakamura proved in
his game with Gyimesi that White retains some annoying pressure by means of 12.¥b5! Therefore Black's main
option is 11...b6 when White brings his ¥ to d3. In the PGN-file you can see that Black has a choice of where to
develop the ¤ at move 13. After 13...¤c6 the critical move seems to be 14.d5!? leading to double-edged play,
though both Alekseev and Onischuk only drew their games in this variation. Socko has a strong preference for
13...¤d7, but failed to reach comfortable equality in his encounters with Stefanova and Gyimesi. In the diagram
position the Polish GM decided to enter a worse ending with 16...£b8?, though 16...£a8 might instead have
been a narrow escape for Black.

The Semi-Slav with 5...a6 used to be quite popular a couple of years ago, but it's hardly seen in top games
anymore. In CVO 118 we provided an update on 6.£c2, and in this issue we take a look at the more flexible
6.b3. On move 10 White has a wide range of choices and the last word certainly hasn't been spoken yet about
10.¦e1!? Last year Bacrot put Rublevsky into deep trouble, but then let his advantage slip away. In Laznicka-
Matlakov Black therefore deviated with 15...¦e8, and a very interesting strategic battle commenced. White aims
to get control over the central darks squares e5 and f4 while also intending to restrict Black's possibilities of
bringing his light-squared ¥ into play. In the diagram position Black decided to sacrifice on h3, as alternatives
also don't seem entirely satisfactory. A possible improvement for Black might be 16...b6!?, as transferring the ¤
to g5 via h7 doesn't fit into Black's positional plans.

Socko-Bartel, Polish Championship (Warsaw), 2012
If White can play ¤g3 his space advantage would enable him to build up attacking chances against the black
¢. Apparently such a scenario didn't appeal to Bartel, who instead preferred to seize the initiative himself.
16...¤fxe4!? 17.¥xe4 ¤xe4 18.¦xe4 f5 19.gxf5 ¥xf5 20.¤g3
20.¦e3 also comes into consideration, though
after 20...£d7 Black retains similar compensation for the material investment.
20...£d7!
Obviously Black isn
’
t
interested in restoring the material balance with 20...¥xe4? 21.¤xe4 when the ¤s have perfect control of the
middle of the board.
21.¦e1
21.¤xf5 £xf5 22.¦e3 ¥d8! with the idea of 23...¥b6 gives Black a dangerous
initiative.
21...¥xh3 22.¤h2 ¦f6 23.¥e3 ¦bf8
Black has two pawns for the ¤, but more importantly all his forces
are eyeing the kingside. In practical terms White

Saric-Huschenbeth, Bundesliga (Hockenheim), 2012
It looks like White has started the game in a fairly positional manner, but the truth is that he had quite aggressive
intentions:
18.g4!
Grabbing the initiative on the kingside.
18...h6?!
This turns out to be too risky. Better was the
immediate 18...¥c6! 19.g5 (19.¥xc5 ¥xc5 20.£xc5 ¦d2 21.¦ac1 £f4 with compensation) 19...¤d7 but of course
White can keep going with 20.f4.
19.h4 ¥c6 20.g5 hxg5 21.hxg5 ¤h7 22.£h4 ¤f8 23.f4 ¤g6 24.£h3
A deadly
white ¦ switch can hardly be prevented at this point.

24...¦d4!? had to be tried.
25.e5 ¥e7 26.¦f2!
and
it was over quickly:
